Progress on the movie version of The Last of Us - one of this generation's most popular and critically acclaimed video games - has stalled.
Naughty Dog creative director Neil Druckmann told IGN that despite strong script that saw it reach to the point of having a table read, the project had entered "development hell".
"There hasn't been any work done on it in over a year and a half," he said.
Released in 2013, The Last of Us won many game of the year awards thanks to its post-apocalyptic tale of two survivors: hardman Joel and his teen sidekick Ellie.
That the movie version has a decent script puts it ahead of the Uncharted movie, which Naughty Dog is only "somewhat involved" in.
Druckman said in the case of that movie, a new writer is on board and currently tackling the relationships between Elena, Nate and Sully.
"Our approach is just to steer them back to those relationships," he said.
"The most important part to get right is Nathan Drake, Nathan Drake's relationship with Elena and Nathan Drake's relationship with Sullivan. If you don't get that right, I don't think the film's going to work. If you get that core right, there's a chance it could work."
Sony has the Uncharted film slated for a June 30, 2017 release. Uncharted 4 is due for release on May 10.
